PREFACE. 



This eleventh Decade gives illustrations in the first plate, 

 No. 101, of the only Victorian specimen known of the great 

 Luth, or Leathery Turtle, the largest of the living Chelonians, 

 and certainly identical with the Old World and American 

 examples. 



The second plate, 102, gives the first recognisable figure of 

 one of the most extraordinary of Australian Lizards, the Rugged 

 Stump-tail, or Shingle-hack, Lizard; the short head-like tail, and 

 very large, thick, rugged scales of which suggest two of the 

 popular names given to it. 



The next plate, 103, shows one of what I venture to call 

 our " Worm- Snakes," the Typhlops nigrescens, which burrows 

 in the light soils of the warm northern part of the colony, 

 and is often found in ants' nests. 



The fourth plate, 101, is of great interest, not only as giving 

 the first accurate figure of the most famous of all Sharks, the 

 Basking Shark, the largest of all known fishes (upwards of thirty 

 feet long), but as representing the only recorded occurrence of 

 the species south of the Equator. The food has now for the first 

 time been identified with certainty as a very minute Pteropodous
